The previous file used a non-standard preamble ("Wren uses the MIT License:")
and included an extra parenthetical clarification about binary distributions.
This commit rewrites the license body to exactly follow the standard MIT
License template published at https://choosealicense.com/licenses/mit/,
removes the custom header, and normalizes line wrapping so that GitHub and
other license detection tools correctly identify the project as MIT-licensed.
This commit introduces a LICENSE file containing the full text of the MIT License, attributed to Robert Nystrom (2013), which governs the distribution and use of the Wren software.
